IBM Security C1000-162 Exam Questions and Answers PDF

The magnitude rating of an offense in QRadar is calculated based on relevance, severity, and credibility. Relevance determines the impact on the network, credibility indicates the integrity of the offense, and severity represents the level of threat. QRadar uses complex algorithms to calculate and periodically re-evaluate the offense magnitude rating​​.

QRadar will mark an Event offense as dormant if no new events or flows occur within 30 minutes. However, if QRadar did not process any events within 4 hours, this also triggers the offense to become dormant. Once dormant, the offense remains in this state for 5 days unless new events or flows are added​​​​.

In the Reports tab of QRadar, the message "Queued (position in the queue)" indicates that the report is queued for generation. The message provides the position of the report within the generation queue, which helps users understand the report's status and expected generation time​

The Ariel Query Language (AQL) is the internal structured language used in QRadar for interacting with the Ariel database, which stores event and flow data. AQL allows users to perform complex queries to extract, filter, and analyze this data, enabling detailed investigations and insights into security incidents and network activity. By using AQL, analysts can tailor their queries to meet specific informational needs, making it a powerful tool for data extraction and manipulation within the QRadar environment​​.
